Benefits of technology
The invention is a compact and light bicycle hydraulic brake clamp that includes a clamp and two piston assemblies. The clamp has slots for receiving brake disks and a through hole for a separation board. The separation board is securely engaged with the through hole via the slots. The two piston assemblies are installed in the slots. The structure of the clamp is simplified and compact. The technical effects of the invention include improving the shortcomings of conventional hydraulic brake clamps by making them lighter and more compact.
Problems solved by technology
A conventional hydraulic brake clamp used for bicycle brake system known to application includes some shortcomings such as leakage, complicatedly manufacturing processes, high assembly cost and unstable structures.
However, there are still some defects existed for the improvements.
If the cap would be overly rotated and the thread would be damaged, the hydraulic oil would leak from the cap.
The cap connected to the aperture of the clamp is not well sealed.
Thus, any impact to the cap could damage the connection and let the hydraulic oil leak.
Second, when the cap is tightly and threadedly connected to the clamp, there is no proper stop provided to acknowledge the assembler to stop rotating the cap.
If the cap is overly rotated, the cap is damaged.

Embodiment Construction
[0017]Referring to FIGS. 1 to 4, a bicycle hydraulic brake clamp in accordance with the present invention comprises a clamp 1, two piston assemblies 2 and a separation board 3. The clamp 1 is an integrally formed part to improve the shortcomings of the conventional hydraulic brake clamp that is composed of two parts.
[0018]The clamp 1 has a first slot 11 defined on the middle thereof for receiving a brake disk therein. Therefore, the interaction between the clamp 1 and the brake disk causes bicycles to slow down. A second slot 12 and a third slot 13 are respectively defined in the two sides of the clamp 1. The first, the second and the third slots 11, 12, 13 are in communication with each other. A through hole 131 is defined through the clamp 1 and communicates with the third slot 13.
[0019]The two piston assemblies 2 are respectively installed in the second and the third slots 12, 13 via the first slot 11. Each of the piston assemblies 2 comprises a locking ring 21, a bolt 22, a push...

A bicycle hydraulic brake clamp includes a clamp, two piston assemblies and a separation board. The clamp has a first slot defined on the middle thereof so that a brake disk is received therein. A second slot and a third slot are respectively defined in two sides of the clamp. A through hole is defined through the clamp and communicates with the third slot. The separation board is fixedly engaged with the through hole via the first slot by a way of welding. The two piston assemblies are respectively installed in the second and third slots via the first slot. The separation board is securely engaged with the through hole so as not only to prevent the separation board from dropping from the clamp by exterior impact, but also to protect the separation board from being damaged by the exterior impact.
Description
FIELD OF THE INVENTION [0001]The present invention relates to a hydraulic brake clamp, and more particularly, to a compact and light hydraulic brake clamp for bicycles.BACKGROUND OF THE INVENTION [0002]A conventional hydraulic brake clamp used for bicycle brake system known to application includes some shortcomings such as leakage, complicatedly manufacturing processes, high assembly cost and unstable structures. The reason is that the conventional hydraulic brake clamp is composed of two parts and the piston is installed into the clamp from outside of the parts.[0003]Applicant provided a cap which is threadedly connected to the aperture of the clamp so as to prevent the piston from dropping out from the clamp and simplifying the structure of the conventional hydraulic brake clamp.[0004]However, there are still some defects existed for the improvements. First, when the brake clamp is assembled, the cap is rotated relative to the clamp. If the cap would be overly rotated and the thre...
